- * Represents an HTML <div> element.
- *
- * The [DivElement] is a generic container for content and does not have any
- * special significance. It is functionally similar to [SpanElement].
- *
- * The [DivElement] is a block-level element, as opposed to [SpanElement],
- * which is an inline-level element.
- *
- * Example usage:
- *
- *     DivElement div = new DivElement();
- *     div.text = 'Here's my new DivElem
- *     document.body.elements.add(elem);
- *
- * See also:
- *
- * * [HTML <div> element](http://www.w3.org/TR/html-markup/div.html) from W3C.
